Bundle: Comparing the Financial Spending and Saving Habits in the US

Fri, 30 Jul 2010 16:45:26 +1100

Bundle [bundle.com] is an original free initiative of open data-sharing that aims to make ordinary people more aware of their everyday spending and saving choices by comparing their financial habits with those of others. Spending patterns are visualized as interactive bubbles, each of which can be filtered by location, age, income or household type, and further refined ("go deep"), refined ("get stats"), or geographically mapped ("map this").

As an innovative twist, any data view that contains a useful insight ("discovery") can be captured, annotated and shared with others on Facebook. For instance, this view should show how household spending in Seattle is more expensive than Brooklyn, New York, while this view tells you something about how much you should spend on clothes when living in Los Angeles.

Bundle claims the benchmark data comes from the U.S. government, from anonymous and aggregated spending transactions from (corporate sponsor) Citi, in addition to third party data providers.

Yes We Canberra: Australian Federal Elections Infographic Television Intro

Thu, 29 Jul 2010 17:07:06 +1100

You might not be aware, but it is federal election time back in Australia. And one of Australia's most successful and internationally exported TV formats, "The Chaser" (well, next to Neighbours, MasterChef, Border Security, My Restaurant Rules and Bondi Rescue, all widely available on European TV) has transformed its name into "Yes! We Can-berra". The satirical program is scheduled as a sort of warming-up act just before a popular live political discussion program Lateline.

Oh well, but what does it have to do with infographics, you say? Well, you should watch its 30-second intro clip below. If only all election statistics could be reported this way...

The Proverbial Wallet: A Wallet Revealing your Financial Situation

Thu, 29 Jul 2010 13:07:37 +1100

The Proverbial Wallet [mit.edu] aims to communicate personal financial information in an ambient manner, to better inform purchasing decisions and improve one's general financial awareness. The design concept consists of electronically augmenting an everyday wallet to make it capable of providing subtle haptic and visual feedback based on the personal financial metrics of the wearer.

. The Peacock wallet prototype appears to physically grow and shrink to reflect the user's
current account balance. Wearers will feel a subtle tightness or looseness in their pocket that persists until their account balance changes. In addition, an unusually high balance will result in a wallet large enough to be clearly visible to potential "mates".

. The Mother Bear wallet contains a resistant hinge to protect the money within it, making it difficult to open when people need to be thrifty.

. The Bumblebee wallet prototype vibrates whenever the bank processes a personal transaction, alerting people to potential fraud in real-time.

While the concept pictures certainly look attractive, the authors John Kestner, Daniel
Leithinger, Jaekyung Jung and Michelle Petersen have also made some working prototypes, which can be explored in their paper.

IBM's Rendition of the World Factbook as an Interactive Dashboard

Wed, 28 Jul 2010 17:19:22 +1100

Next to its sexy visualization for-the-masses called Many Eyes, data-crazy IBM has some more serious clientèle to cater for. Its "ILOG Elixir development team" shows off the data rendering capabilities of Adobe Flex through the online demonstration World Factbook Dashboard [ibm.com]. The heavily stylized application contains various gauges, 3D column and pie charts, a radar chart, a treemap and a world map view, which are all coordinated and synced through some very smooth animated effects. The different views also allow for the dynamic, user-driven scaling of the color legend, while countries can be compared by those in their immediate neighborhood.

Exploring such data-rich dashboards seem to provide me with a weird sensation I cannot put my finger on. Is it information-interaction-overload? Is it visual aesthetics? Or a mismatch in intended target audience? Why is this (personal) impression so different from, let's say, the recent World Bank Data Dashboard? I am not sure...

More information about this dashboard is available here. For those interested, there is also a similar real-time dashboard showing web statistics here.

Wikileaks' Afghanistan War Logs and Its Visualization

Tue, 27 Jul 2010 14:54:02 +1100

The Guardian's Datablog just released an interesting run-through of how they had to deal with the raw data from the recent Afghanistan War Logs, a 6-year archive of classified military documents. The New York Times also released a view behind the verification and the data formatting process.

For anyone with an interest in datajournalism, this all makes an interesting read. For instance, with the main goal of making the huge and complex data understandable and navigable for expert journalists with a tight timeframe, Datablog explains in detail how the 92,201 rows of MS Excel data had to be ordered and categorized.

In the meantime, the first War Logs visualizations have appeared:
. Newspaper-version map of IED attacks between 2006-2009
. Interactive map of all 16,000 IED attacks

Let's hope The New York Times will make the list a bit longer, making such long enumerations as appeared here a rare exception...

Visualizing the Aging World Population

Tue, 27 Jul 2010 13:45:59 +1100

One of the few data graphs I still remember well from my childhood, revealed the division of my birth country's population by age. The rising, big bulge in the middle would mean inevitable doom, so said my school teacher, as the retirement and health costs for these people (while conveniently skipping himself) would have to be paid by the slender part of the graph (pointing to us). I never looked the same to my parents since then. Now, about 20 years later, his words are still true.

The latest graph [ge.com] released by GE illustrates the aging population problem in the world by contrasting the demographic statistics of 8 different industrialized countries. Designed by Fathom Information Design, the company recently set up by viz-guru Benjamin Fry, the applet allows users to select pairs of countries, of which the data can be cycled from 1950 to 2050.

While revealing the statistical trends, the visualization still seems to come up short to describe the causal events or harsh consequences behind the phenomena present in the data, which could actually be quite intriguing. Would you agree?

In the meantime, GE is already looking for a "Data Visualization Leader", with some amazing skills in creative, technical as well as management areas.

Pulse of the Nation: U.S. Mood throughout the Day Inferred from Twitter

Fri, 23 Jul 2010 09:42:45 +1100

The scientific study "Pulse of the Nation: U.S. Mood throughout the Day Inferred from Twitter" [ccs.neu.edu] illustrates the varying mood in the U.S., as inferred after analyzing over 300 million tweets that were created over the course of the day. Various density-preserving cartograms and a time-animated video were produced to capture important large-scale trends.

The researchers analyzed all public tweets posted between September 2006 and August 2009, and filtered those whom orginated from a US location and those that contained words included in the psychological word-rating system called Affective Norms for English Words, resulting in a collection of 300 million tweets. Through a natural language processing algorithm called Sentiment Analysis, each tweet was assigned a mood score based on the number of positive or negative words it contained. Out of the resulting data, they then calculated the average mood score of all the users living in a state hour by hour which formed the basis of a series of time-varying mood maps.

One of the interesting patterns shows how the West Coast mood follows the same pattern as the East, with a 3-hour time-zone delay, indicating that Each Coast experiences the same time-dependent swings. Weekends were observed to be happier than weekdays. The peak in the overall tweet mood score is observed on Sunday mornings, and the trough occurs on Thursday evenings.

YouTube Adds View Tracking Data Visualization Dashboard

Thu, 22 Jul 2010 14:58:40 +1100

While YouTube Insight already provided detailed feedback about the performance of videos to their creators, a (seemingly) recent development has made this information now public and for all to see. Well, I could not find any other online medium reporting on this, so either this has been around since quite some time, or was not deemed newsworthy enough.

Each YouTube movie now features a detailed data visualization dashboard, which shows the number of views over time, including the exact occurrences when the movie was embedded at an external source. While competitor Vimeo has since long listed the number of views and 'likes' in bottom right corner, the YouTube version takes a more contextual approach.

In the usage statistics of great infographic movie "Growing Up", for example, one can clearly perceive the impact of different design blogs on the number of views, next to the effect on the movie's Ratings, Comments and Favorites, plus a breakdown on age and geographical location. This feature can be revealed by simply clicking next to the arrow icon near the number of views.

In other social media statistics developments, YouTube now also features a speed dashboard, which contrasts the performance of your online connection, while popular link shortener bit.ly has recently rolled out a sophisticated analytics dashboard as well.

Representing the US Military Budget by 3D Computer Graphics Imagery

Discovery Exhibition: Hierarchical Clustering Explorer

Tue, 20 Jul 2010 13:58:33 +1100

After the "ParSets" impact story of a few week ago, here is our second entry from last year's Discovery Exhibition, titled "Hierarchical Clustering Explorer" by Jinwook Seo.

Hierarchical Clustering Explorer (HCE) is a data visualization tool designed for biologists who are trying to understand the functions of genes. To study genes, biologists run experiments using tools called microarrays which measure gene activities under different experimental conditions. Common approaches to finding patterns in the data of these experiments is to run clustering methods but there are few tools that allow for interactive exploration of this data, which can also be quite huge in size. HCE is an example of such a tool that was designed to help in the analysis of clustered datasets.

This image shows three different clusters of genes related to muscle regeneration. These were identified using the tool and in the picture are currently selected for further exploration.

Impact
Since HCE was developed for microarray data analysis at the beginning, it is well-known to microarray researchers. There are quite a few biology journal papers that cited HCE as an analysis tool for their microarray data. The most prevalent usage pattern in this field is that users play with features of the system until they see a meaningful separation of clusters. Then they identify clusters that deserve further investigations and look at them in other views of HCE. Once they find such clusters, they often generate a hypothesis that genes in the cluster might have similar or related biological functions to focus/target genes. Using this discovery process, a team of molecular biologists at the Children's Research Institute could identify 18 genes involved in the muscle regeneration process.

Currently, there are many microarray researchers who use HCE as their primary tool for microarray data exploration and a future version has been requested. The good news is that the authors of the tool have recently received funding to develop a newer, and hopefully even better, version of HCE.

Please visit the Discovery Exhibition entry for further information on unexpected impact in teaching and meteorology that the tool has received. If are personally interested in these types of impact stories, please consider submitting to the exhibit. The deadline is now, and please check the call for participation.

Top Secret America: Visualizing the National Security Buildup in the U.S.

Mon, 19 Jul 2010 18:27:21 +1100

"Top Secret America" [washingtonpost.com] is an extensive investigative project of the Washington Post that describes the huge national security buildup in the United States after the September 11 attacks. More than a dozen Washington Post journalists spent 2 years developing the database, which was put together by compiling hundreds of thousands of public records of government organizations and private-sector companies. From these records, The Washington Post identified 45 government organizations (for example, the FBI) engaged in top-secret work and determined that those 45 organizations could be broken down into 1,271 sub-units (for example, the Terrorist Screening Center of the FBI). At the private-sector level, The Post identified 1,931 companies engaged in top-secret work for the government, ranging from the "nuclear operations" by AT&T to the "cyber operations" of Abraxas.

The project also seems to put the newspaper on the data-visualization-as-journalism map, still dominated by the New York Times infographics department.

The "Top Secret Network of Government and its Contractors" explores the relationships between government organizations and the types of work being done in "Top Secret America". A radial table can be rearranged according to 3 questions: "Who does the most types of work?", "Who works with the most companies?" and "Who does which types of work?" The data can be further filtered along several categories, such as Intelligence, Military or Weapons Technology.
The "Where is Top Secret America?" shows the locations of government organizations and companies that deal with security (although stops short explicitly naming them?). One can also query for specific companies, or search the data for themselves.

Data Visualization Review: Gephi, Free Graph Exploration Software

Thu, 15 Jul 2010 15:07:24 +1100

I do not often get to play with networks, yet I find them fascinating and full of knowledge gathering potential. The data visualization works of Moritz Stefaner, Jer Thorp, and Mark Lombardi captivate me. I am intrigued by relationships, how we perceive them, and how we can understand them.

Gephi, the "Open Graph Viz Platform", is not just for the hobbiest node nerd. It is a hardcore, professional tool for network researchers and other smarty pants. If you know the difference between Yifan Hu and Fruchterman Reingold, then you can use this tool effectively. But you do not need to be rich, as the software is completely free to download and use.

So what is Gephi capable off?

Pros
— Options! Lots and lots of options. Network layout, fonts, edge size, node size, borders, colors, labels, etc. You name it, it's probably in there.
— Grouping. Ability to group nodes by data points.
— Community-detection. Gephi can identify groups by using its modularity algorithm.
— Reduction. The ability to filter out practically anything in order to make a more coherent graph.
— Statistics! I'm sure this is really cool, but I'm not educated enough to know. If you know your Eigenvector Centrality from your Average Clustering Coefficient, then you will love this feature.
— Export. You can export your graph as SVG or PDF.

Cons
— Interface is a bit cluttered. Multiple levels of tabs and redundant buttons make it a bit confusing to navigate. This will probably wane with long term use of the tool.
— A bit buggy. The undo, cut, paste, etc. menu items never seem to work for me. Certain settings remained "on" even after I turned them "off."
— No documentation. There are a couple of user guides that are helpful, but lacking.

Review
Overall, Gephi is a useful and interesting tool. It allows you to explore, create, and analyze network graphs in a fairly easy way. It offers many visualization options for any type of network and supports up to one million nodes and edges.

There are some plugins available for Gephi that extend the functionality. I used one called GeoLayout to make the Minard graph below.

The only thing keeping Gephi from being a professional grade tool is its bugginess and lack of documentation. If its development community can sustain it, Gephi should be able to improve and become a more robust software tool.

For the Purists
Gephi is a purist's delight. All the network graphing functionality is based on cold, hard science. If you recently read the Holten and van Wijk paper, you will like Gephi. It has loads of options but all within the confines of good taste.

For the Aestheticians
While there are no progressive or experimental ways of graphing networks with Gephi, you might still be happy to use it for its ease of exploration. It allows you to customize the look of your graph in many ways. It allows for proportional labels and label truncation, different types of edges based on if its directional or not, and everything from node color to group highlighting. I have to say, I was impressed by the level of visual customization. There are a few things that are overlooked, however, such as overlapping labels, annotation, and so forth. Since the graphs are SVG exportable, at least some of these visual problems can be rectified.

Two nerdy charts of network statistics that Gephi will output.

Question: Is This the Little Book of Shocking Infographics?

Wed, 14 Jul 2010 11:25:44 +1100

There is another small ripple in the force that keeps together beauty and functionality, now Nicholas Felton put forward a short critique of a recently released infographic book titled "The Little Book of Shocking Global Facts".

Pitched as the combination of "startling graphic imagery with truly shocking facts gathered from the world's most authoritative sources", the book seems not to have convinced everyone. Reviewed instead as a "compendium of awful graphics", its illustrations seem to ignore even the most basic rules of good infographic design, while the lack of any source material does not make the resulting insights trustworthy.

Strange. In spite of its clear subject relevancy for the core audience of this blog, I was not aware of the book, yet this introduction makes a memorable impression...

So, what is your take on the value of this book? Is there any danger in this sort of coffee table books filled with potentially life-changing illustrative "facts" that might withhold any sensemaking, yet are a marvel to browse through?

To make up your opinion, you can browse through some high-rez examples below (click on the images for large versions), download a book preview here, or buy the book or its little sister The Little Book of Shocking Eco Facts.

"1945-1998" [ctbto.org] by Isao Hashimoto (2003) displays all the 2,053 nuclear explosions and tests conducted in various parts of the globe, over time. The year and month are shown at the top right corner. Each detonation is flashed on a stylized world map, accompanied by a minimalistic computer sound. The years roll by at one month per second.

What starts of as a slow succession of a few blimps, rapidly becomes a display of fireworks.
